Build a virtual bookshelf of free Ruby and Rails books:

If you’re just getting into Ruby or Rails now, and looking for some light reading, you’re in luck. Publishers like the Pragmatic Programmers, O’Reilly, Manning Publications, and others have tons of books available to help you learn. You could easily spend a few hundred dollars building a bookshelf of Ruby references. There are also some good free books to peruse online (or download) to get started or augment your collection.
